SQLDERlNG-IRONf SPECIPICATION formingpart of Letters Patent No. 309,281, dated December 16, 1884.

, Application filed October 212, I883. Renewed July 1, 1884. (Nomodeh) .To all whom it may concern:

Be it known that I, AUGUST F. ZIMMER- LING, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Soldering-Irons; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to combined selfheating soldering-irons and blow-pipes, and will In the drawings, Figure 1 is aside elevation of my improved soldering-iromand Fig. 2 is a vertical section through center of same.

A is thehandle,which is madehollow to contain any of the gaseous liquids generally used for heating purposes. The reservoir thus formed is preferably divided in two parts-A', the supply-reservoir, and A, the feed-reservoir, the connection being made between them by thesupply-pi1i e a, which empties insaid feedreservoir A near the front end of same. From said reservoir A two feed-pipes, B B, opening in same through perforations formed on the same diainetrioal line near the rim of shaped pipe-coupling, (J, the hollow stem 0 of which forms the seat of the feed-valve D. Said valve D has the milled head (I, and a thread is cut around the middle part of its stem 0, to

coupling stem 0, which is also threaded on its outside for the'stuffing screw-box f. A suitable curve is given to said feed-pipes B B to allow of the space requisite to conveniently turn the milled head (Z of said feed-valve D, whereby the conical point of said valve may be brought close against the similarly-formed the gas-supply, or kept at a more or less minute distance from it to allow said gas to supply the flame. Said front stem, 0, of coupling O is threaded on the outside to fasten the vent-pipe E, which screws on the same, to rest its flanged base 9 against the arms of said pipecoupling 0. From about the middle of its length forward said vent-pipeEis slightly enlarged, and in the shoulder 0 thus formed in it a series of inclined holes, 0 e e, are drilled,

are induced by the flow of gas toward the front end of said pipe E. For the same purpose other holes, 6 0 through said pipe E are drilled,so that their center is just opposite the end stem, 0, of the pipe-coupling G. The enlarged part of said vent-pipe E is threaded just above the shoulder c, and thereon is screwedv the rear end of the heating-pipe F, an air-space equal to the depth of the thread being left between the two connecting-pipes. This is used in connection with the holes (2 e e, drilled just above the thread formed on the inside of heating-pipe base, to serve as additional vents for the air-supply. The heatingpipe F, of suitable length and diameter, has a series of perforations, a a a a, the rear ones of which are drilled,so that their center is just opposite the front end of the vent-pipe E, which projects into said heating-pipe F. Its front end is somewhat enlarged,in order to eX- pose more of the metal to the flame close to the soldering-tip G. This forms a separate part, and is provided on its base with a thread, which screws inside of the heating-pipe F. IVithout said tip G my self-heating solderingiron becomes ablow-pipe, the manipulation of which in both cases is absolutely the same as in ordinary soldering-irons and blow-pipes, except as to the heating of the same.

As to that part which constitutes my imp rovement, the operation is reduced to the filling of the reservoirs with the desired liquid. This done, as soon as the feed-valve is screwed upward for a proper feed, the vent-pipe E is exposed to the light, and in a few seconds enough of heat is produced to convert the fluid into dry gas, which takes fire as it blows out in the vent-pipe E from the valve-opening;

the ignited jet shoots forward into the heat-' ing-pipe F, inducing through the ventholes e ec e c e the air currents to supply the oxygen needed for its flame.

Having thus described myinventioni, what I claim as new, and desire to secure by Letters Patent, is-

1. In a soldering-iron, the heating-pipe F, having jet-holes a a and vent-holes c e, in combination with pipe E, having vent-holes e and 6 with feed-valve D on pipe-coupling O, feed-pipes B B, and handle A, having reservoirs A and A and connections, substantending from the feed-reservoir to the pipe tially as shown and described, and for the purcoupling, and straddling or inclosing the pose set forth. feed-valve, substantially as set forth.

2. In a soldering-iron, the soldering-tip G, I In testimony that I claim the foregoing I 5 in combination with the heating-pipe F, venthave hereunto set my hand, at Milwaukee, in

pipe E, valve D, feed-pipes B B, and handle the county of Milwaukee and State of Vis- A and connections, substantially as shown and described, and for the purpose set forth.

3. In a soldering-iron, the combination, with 10 the handle A, having supply-reservoir and feed-reservoir, heating-pipe F, and coupling 0, with feed-valve D, and two feed-pipes eX- cousin, in the presence of two'witnesses.
